HIGH-POWER MEDIUM-VOLTAGE DRIVE POWER CELL
First Claim
1. A high-power medium-voltage drive power cell, comprising:
- a power element subunit, comprising;
a rectifier module for rectifying a three-phase AC input voltage to obtain a DC voltage;
an IGBT (Insulated Gate Bipolar Transistor) inverter bridge electrically connected to a capacitor subunit for converting the DC voltage into an AC voltage of which the frequency, the amplitude and the phase are adjustable;
a bypass module connected to the IGBT inverter bridge for providing the bypass function when the IGBT inverter bridge functions abnormally; and
a heat pipe heat sink having a base plate on both sides of which power elements of the high-power medium-voltage drive power cell are disposed; and
a capacitor subunit comprising capacitors and a housing, wherein the capacitor subunit is electrically connected to the rectifier module and the IGBT inverter bridge, thereby filtering the DC voltage rectified and then transferring the DC voltage filtered to the IGBT inverter bridge.
